Eight long years after All For One is destroyed, Izuku Midoriya, now a history teacher at UA, longs for hero work once more.
Luckily for him, his mentor and his friends bestowed him with his own 'super-suit', in hopes that it would make up for his quirkless form.
Now tasked with getting to the bottom of the alarming rates of people being born quirkless, Izuku sets out once again as all he's ever dreamed of being: a hero.
Which would be a lot easier if he weren't being haunted by a pointedly annoying super villain's ghost.

TLDR; Vestige Tomura Shigaraki and pro hero Izuku Midoriya. They're stuck together and are forced to bond, basically.
